real-time streaming technology and overcoming latency

블랙티비 주소

The essence of sports broadcasting lies in its "real-time" capability. However, in a digital broadcasting environment, latency is inevitable during the physical signal transmission process. The phenomenon of hearing the cheers for a goal from a neighboring house before one can be heard was the biggest challenge streaming technology had to overcome. 5G technology has become the decisive key to solving this problem through its ultra-low latency characteristics. In stadiums equipped with 5G infrastructure, the process of transmitting ultra-high-definition video captured by hundreds of cameras to a central server and then delivering it to users takes place in milliseconds (ms). This has gone beyond a mere speed issue and has fostered the birth of new broadcasting techniques. A prime example is "free-viewpoint broadcasting." Viewers are not limited to watching only the screens set by the broadcasting team; instead, they can follow their favorite players or directly select angles from specific locations within the stadium. Furthermore, 5G broadcasting combined with artificial intelligence (AI) visualizes the vast amount of data generated during the game in real time. In soccer matches, the instantaneous overlay of graphics on the screen—such as a player's current speed, shooting probability, and activity level (Heatmap)—is made possible by wide-bandwidth 5G communication networks. These technological advancements are transforming viewers from passive observers into active analysts. Future broadcasting technology is moving toward integrating Virtual Reality (VR) and Augmented Reality (AR) to perfectly realize a realistic, immersive experience, making viewers feel as if they are sitting in a VIP seat at the stadium, even from the comfort of their living rooms.
